ECM connector cleaner

[Wen Yen Chan]

Hello,

Poly Phenyl Ether seems to work well. Stabilant 22A works even better but
is bloody expensive. I prefer Stabilant 22A as it is a non conductive
liquid which becomes conductive when there is arcing between the contacts.
I use Stabilant 22A at work on connectors which are worn out but a real
pain to replace (200 pin connectors between rows of surface mount parts
for example).

He said that they, in his shop, pull the connectors and spray them with WD40.  Well, gasp!  Not trusting WD40 to the task I used CRC contact cleaner, worked the connectors in and out, and low and behold, the stumble disappeared!!!! (:>  ZM000000M

I thought about removing the connectors and using connectors like on my computer, that could be locked into place by set screws.  This is a lot of work.  Surely there must be something that can be sprayed, that will do the job!
